a few questions regarding steering gears and 3/4 ton frames.

[ghetto_superman]

ok heres my questions.
ive got a P/S box from a 69/70 3/4ton on my 68 halfton. it steers ok.. but its a slow ratio and i want to quicken it up. a lot. i was wondering- can a guy take just the gears out of say, a camaro box, and put them into our box? that would be pretty sweet.
next question.
is there any difference between actual frames from a halfton 2wd and a 3/4ton 2wd? cause the thing is, ive got 2 swb frames (one will be for sale eventually) and i am planning on stretching my cab a bit..originally i was gonna hack them both up to make one longer one, but i realized it would be RETARDED to sacrifice 2 good swb frames from the world if i could just shorten a lwb one.
so ive GOT a 3/4 ton frame (front cab mounts back anyway) and was wondering if it would be worth it to use that frame, if its actually any stronger, cause id still have to shorten it under the cab, add t-arms, t-arm crossmember, spring pockets, shock mounts.. and attach a front clip.. which would pry be halfton rated anyway. OR should i just find a halfton 2wd lwb frame and go from there??
MAN maybe i just answered my own question..!! any suggestions greatly appreciated though...
